HINGE FOR WINDOW-SCREENS.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed June 4,1906. Serial No. 319,993.

To all whom it may concern.-

Be it known that I, BENJAMIN F. DOUG- LASS, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Hinges for Window-Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to hinges for window screens so constructed as to provide for the mounting of screens corresponding in height to the heights of windows in order that the entire window-way may be protected against the ingress of flies when either the lower, or upper sash is opened without liability of flies passing through the Window opening.

Figure I is a perspective view of a window with a screen located therein and supported Fig. II is a vertical section taken through the window and screen. Fig. III is a pers ective View showing one corner of the win ow screen, the hanger bracket carried thereby and one of the bracket hooks which said hanger bracket engages.

A designates a window frame of any common form and B a window sill.

1 designates bracket hooks that are secured by screws or other suitable means of fastening 2, to the window frame preferably immediately below the lintel. Each of these bracket hooks is provided with a notch 2 in its outer portion and terminates in a hook point 3 that extends upwardly from said notch and preferably has an inwardly curved rear edge 4 as seen in Fig. III. When the bracket hooks are applied to a window frame they are so positioned that the arms thereof which are provided with the notches and hook points project beyond the window frame 1n an outward direction relative to the window frame as seen most clearly in Fig. I.

5 designates hanger brackets secured to the frame of a window screen C by screws or other suitable means. Each of these hanger brackets is provided with a projectin arm 6 that extends beyond one of the side aces of the screen and terminates in a flat li 7 which is of approximately the same widt as the bottom of the notch 2' and extends at screen, the screen is readily fitted into the Window opening by first placing the screen in the position illustrated in dotted lines at the top of Fig. II; then lowering the top end of the screen which bears the hanger hooks'until the hanger brackets pass into juxtaposition with the bracket hooks 1 and the lips-7 of said hanger brackets enter into the notches 2 in the bracket hooks at the rear of the hook points 3. The screen is then lowered while suspended by the inter-engaging hanger brackets and bracket hooks and drawn into the window frame where it may be readily secured by any suitable means, such as a hook 8, as seen in Fig. II. The object in curving the edge 4 of the hook point 3 inwardly is to prevent the hinge members, carried by the screen frame, from being elevated to disengage their lips 7 from the hook points until the screen frame has been thrown outwardly to a SllfllGlGIlt degree to permit separation of the hinge members without injury to said members.

I claim:

The combination with a window screen, of means for securing the screen to a window frame; said means comprising a fiat bracket hook for application to a window frame and having a notch and terminating in a hook point having an inwardly curved rear edge adjacent to said notch, and a han er bracket attached to the window screen an terminating in a flat lip extending at a right angle to its body and adapted to engage said hook point and seat in said notch; said lip being approximately of the same width as the bottom of the notch.
